AMOS ELLMAKER JOHNSON, OF NORTHUMBEBLAND, PENNSYLVANIA.

a EDUCATIONAL GAME DEVICE.

To all whom it may concern:

Be it known .that I, AMos E. JoHNsoN, a citizen of the United States,and a resident of Northumberland, in the county of Nortliumberland andState of Pennsylvania, have invented certain new and useful Improvementsin Educational Game Devices; and I do hereby declare the following to bea full, clear, and exact description of the invention, such as willenable others skilled in the art to which it appertains to make and usethe same.

This invention relates to an improved educational game device, oneobject of the invention being to .provide a device of this characterwhich shall be susceptible of wide rangeof useful instruction impartedin an entertaining and attractive manner, and to so construct the devicethat it may comprise members which shall be interchangeable andreversible to adapt it for educational games differing more or less inspecific characteristics.

With these and other objects in view, the invention consists in certainnovel features of construction and combinations and arrangements ofparts as hereinafter set forth and pointed out in the claims. I

In the accompanying drawings; Figure 1 is a plan View of a game deviceshowlng an embodiment of my invention; Fig. 2 is a sectional view of thesame, and Fig. 3 is a view illustrating various characters of educational data which may be placed upon various disks.

1 represents a table, which may be made of wood or any other suitablematerial and which may have a circular form. I prefer to support thistable upon legs 2 which may be secured thereto in any suitable manner.The table 1 is provided centrally with a hole for the reception of a hubor socket piece 8, which latter is of sufficient height to project somedistance above the plane of theupper face of the table, and it may beprovided with an annular shoulder 4 to engage the central portion of adisk 5. located upon the table and through which said hub or socketpiece passes.

My improved device comprises a plurality of disks 5 and the'hub orsocket piece may be removably attached to the table, whereby the disksmay be interchanged or reversed, as desired. The -hub or socket pieceserves as a mounting for a pin 6 which depends from a pointer or arrow7, the lat= Specification of Letters Patent. Application filed ma 8,1915. Serial No. 26,793.

ter being thus revolubly mounted over the table and the disk thereon.The pin may be removably supported by the hub or socket piece so thatthe arrow may be readily removed without removing the socket piece, topermit the placlng of a diskupon or removable of a disk from the table.

One or both faces of each disk is divided by radial lines 8 and thespaces formed by these lines maybe subdivided by circular lines 9,-sothat a number (preferably about symbols are employed and they maybearranged indiscriminately 1n the spaces of the circular series 0.

In operating the device, one player will cause the rotation of thearrow, and his score will. be the arithmetical deduction, according tothe figures and symbol in the radialseries of spaces a, b, c, where thearrow comes to rest. For instance, if the arrow should come to rest inthe position shown in Fig. 1, the .players score would be, two as 8divided by 4 equals 2. Should the arrow come to rest in line with aradial series of spaces including a minus symbol, the score would be thedifierence be-/ tween the two figures in the spaces w, c, of such radialseries,for instance '8 minus 4 equals 4. In like manner, the stopping ofthe arrow in line with a multiplication symbol, the figures in thespaces would be mul. tiplied to arrive atthe score, and the figures inspaces a and 0 would be added when the arrow stops in line with anaddition symbol. The players will spin the arrow in turn, and the onewho first attains a predetermined score, will be the winner.

Instead of providing the several arithmetical symbols, indiscriminatelyarranged on the same disk, separate disks may be arranged for addition,subtraction, multiplimay be provided with figures and symbols,

on one face and on the reverse side, other characters may beplaced,-such as letters, pictures of buds and animals, or the names orpictures of army generals representing opposing sides 1n a war,-or ifdeslred, sepa' rate disks may be provided tor each class of charactersabove referred to, or any other class of characters.

Various slight changes might be made in the details of constructionWithout departing from the splrit thereof or limiting its scope andhence I do not Wish to restrict myself to the exact details herein setforth.

Having fully described my invention what I claim as new and desire tosecure by Letters-Patent, is

1. An educational game device comprising a table, having a central hole,a removable hub entering said central hole, a plurality of'disks havingcentral holes, held in place on the table by said hub, each of saiddisks having educational matter thereon differing from such matter onthe other disks, whereby said disks may be interchanged and permit theplaying of Various-educational games and a pointer disposed over thetable and provided with a pin revoluhly mounted in said removable hub.

2. An educational device, comprising a table, a removable hub mounted onsaid table and projecting upwardly therefrom, a spinning arrow providedwith a pin mounted in said hub, and a removable disk held in place onsaid table by said hub and having a central hole to accommodate thelatter, said disk having educational data thereon.

3. An educational game device, comprising a spinning arrow and a diskhaving three circular series of spaces, two of series of spacescontaining figures, and the intermediate circular series ofspaces-containing various arithmetical symbols in radial alinement withspaces of the other two circular series.

In testimony whereof, I have signed this specification in the presenceof two subscrib- 5 ing Witnesses. I AMOS ELLMAKER JOHNSON.
